This is a prospective, phase 3 randomized controlled clinical trial. Cervical cancer patients with FIGO stage IB3, Ⅱ A2 or IIB with tumor size> 4 cm will be enrolled. Patients will undergo 2-3 cycles of neoadjuvant chemotherapyradical (NACT) followed by laparotomic or laparoscopic hysterectomy + pelvic lymphadenectomy with cervical cancer foci sealed before dissection of the vagina and without uterine manipulator. Patients meet criteria of adjuvant therapy according to NCCN guideline after surgery will be weeded out, and who do not meet criteria of adjuvant therapy will be randomly selected to undergo adjuvant chemotherapy or just follow-up visit. The primary endpoint was disease-free survival (DFS) rate at 5 year. The secondary endpoints were 5-year overall survival (OS), safety and quality of life.

Inclusion Criteria:

1. Clinical stage IB3-IIB cervical cancer (FIGO, 2018 standard) with the tumor diameter > 4cm before treatment.
